Weakness Name
Integer Coercion Error
Description
Integer coercion refers to a set of flaws pertaining to the type casting, extension, or truncation of primitive data types.
Several flaws fall under the category of integer coercion errors. For the most part, these errors in and of themselves result only in availability and data integrity issues. However, in some circumstances, they may result in other, more complicated security related flaws, such as buffer overflow conditions.
Common Consequences
- Scope:
- Availability
- Impact:
- DoS: Resource Consumption (CPU), DoS: Resource Consumption (Memory), DoS: Crash, Exit, or Restart
- Notes:
- Integer coercion often leads to undefined states of execution resulting in infinite loops or crashes.
- Scope:
- Integrity, Confidentiality, Availability
- Impact:
- Execute Unauthorized Code or Commands
- Notes:
- In some cases, integer coercion errors can lead to exploitable buffer overflow conditions, resulting in the execution of arbitrary code.
- Scope:
- Integrity, Other
- Impact:
- Other
- Notes:
- Integer coercion errors result in an incorrect value being stored for the variable in question.
